3.1 PERFORMANCE CURVES FOR FILTER ASSEMBLY
The total performance curves for element UMC / ULP…
apply to mineral oil with a density of 0.86 kg/dm³ and
a kinematic viscosity of 30 mm²/s.
3.2 MAXIMUM PEAK FLOW RATE
The following maximum permitted peak ow rates (Q
max
)
in l/min are possible for the various sizes:
Information regarding dimensioning:
The hydraulic load on the lter element is primarily
deter mined by the ow rate and the geometry of
the particular lter element. Exceeding the maximum
permitted ow rate (Q
max
) and therefore the permitted
hydraulic load can destroy the lter element.
Even the choice of operating medium can inuence
system performance and lead to problems during use
such as electrostatic discharges.
Adherence to the maximum permitted ow rate should
always be ensured throughout the system project planning
process.
If you have any questions regarding dimensioning
or project planning, please contact the technical sales
department at HYDAC Filtertechnik.
3.3 COVER VERSION
To balance out manufacturing tolerances specically in the
case of plastic tanks, an optional cover version with inte grated
spherical dome is available for the RFB Compact.
This “swivel” version provides perfect balancing of process
related production tolerations in the tank construction.
The maximum tolerances are given in section 4.2.

5. MAINTENANCE
5.1 MAINTENANCE
Design
Please follow the maintenance instructions on the last page!
Installation
Before installing the lter, check the permitted operating
pressure of the system – it must be lower than permitted
operating pressure of the lter. Refer to the identication
plate on the lter!
Start-up
Check that the correct lter element is tted, apply the cover
and secure it. Switch on the hydraulic system and check lter
for leakage.
Vent lter at an appropriate point in the system.
Tightening torques
5.2 CHANGING THE ELEMENT
Removing the element
1. Switch off hydraulic system and release lter pressure
(if necessary release the pressure in the tank).
2. Loosen the cover by turning it anticlockwise
and pull out the cover with the element,
allowing any adhering oil to drip off.
3. Loosen the bayonet connection between cover
and element from the catch with an anticlockwise
rotation and remove cover.
4. Clean cover and examine for mechanical damage.
5. Check Oring – replace if necessary.
Fitting the element
1. Clean all removed parts and check for damage.
Replace damaged parts and ensure that sealing surfaces,
threads and Orings are wetted with clean operating uid.
2. When installing a new lter element (1), check that
the designation corresponds to that of the old element (1).
3. Place element (1) on the cover and turn it clockwise until
the bayonet connection has engaged. For the “swivel”
cover version, align the thread coaxially to the element.
This makes it easier to insert the connection in the tank.
4. Push element with cover into the housing ange
and push the element onto the connection.
5. Place the cover on the thread ange and tighten it
to the stop clockwise and ngertight – recommended
torque 30 Nm. For the “swivel” cover version, ensure
that the thread moves freely – the cover can be tilted
to align it to the internal thread on the ange.
6. Switch on hydraulic system and vent lter at a suitable
point in the system.
7. Check lter for leakage.

Filter elements are to be disposed of

INSTRUCTIONS
7.1 USER INSTRUCTIONS
FOR FILTERS
Caution: lter under pressure:
before any work is carried
out on the lter, ensure the
pressure chamber con cerned
(lter housing) is depressurised.
On no account may any modications
(welding, drilling, opening by force etc.)
be carried out on the lter.
Filter housing must be earthed.
When working on, or in the vicinity of,
hydraulic systems, naked ames,
spark generation and smoking are
forbidden.
Hydraulic oils and waterpolluting uids
must not be allowed to enter the soil,
watercourses or sewer systems.
Please ensure safe and environmen
tally friendly disposal of hydraulic oils
and uids. The relevant regulations
in the country concerned with regard
to ground water pollution, used oil
and waste must be complied with.
Whenever work is carried out on
the lter, be prepared for hot oil
to escape which can cause injury
or scalding as a result of its high
pressure or temperature.
The owner must take
appro priate action (e.g.
air venting) to prevent the
formation of air pockets.
Repairs, maintenance work and com
missioning must only be carried out
by trained personnel. Allow the lter
to cool before handling. The stipula
tions in the machine or system opera
ting instructions must be followed.
Statutory accident prevention regula
tions, safety regulations and safety
data sheets for uids must be ob
served.
This lter must only be put
into operation in conjunction
with a machine or system.
The lter must only be used
as stipulated in the operating instruc
tions of the machine or system.
This lter must only be operated
using hydraulic or lubricating uid.
It is the responsibility of the operator
to comply with the water regulations
of the country concerned.
7.2 MAINTENANCE, GENERAL
This section describes maintenance
work which must be carried out
periodically. The operational safety
and service life of the lter, and
whether it is ready for use, depend
to a large extent on regular and
careful maintenance.
7.3 BASIC PRINCIPLES
This document is for information
purposes and for the avoidance
of dangers during installation,
during the operation of the system
and for the handling of operating
materials.
Safe and economical operation of
the system is only possible if the
installation manual is observed closely.
This installation manual does not
sub stitute the operating instructions
of the device or the system.
The individual installation instructions
for the installed components of the
overall system also apply.
7.4 QUALIFICATIONS OF
PERSONNEL / TARGET GROUP
This installation manual is exclusively
geared towards use by trained
specialists and it must be made
accessible at the place of use.
7.5 INTENDED USE
The lter is only suitable for the ltra
tion of operating uids.
The lter is not useable on its own.
The lter is intended for installation
in a hydraulic system.
Any alternative or more extensive
use shall not be considered intended
use. HYDAC Filtertechnik GmbH will
assume no liability for any loss or
damage as the result thereof.
7.6 MAINTENANCE MEASURES
● Spare parts must conform to the
technical requirements specied
by the manufacturer. This is always
ensured when using original
HYDAC spare parts.
● Tools, working area and devices
are to be kept clean.
● After disassembling the lter,
clean all parts, check them
for damage or wear and replace
them if necessary.
● When changing a lter element,
a high level of cleanliness must
be observed!

7.8 INTERVAL BETWEEN ELEMENT
CHANGES
In principle we recommend that
the lter element is changed after
one year of operation at the latest.
If no external clogging indicator can
be tted, we recommend changing
the elements at specic intervals
(the frequency of changing the lter
elements depends on the lter calcu
la tion and the conditions under which
the lter is operated). When lter
ele ments are subject to high dynamic
loading it may prove necessary to
change them more frequently.
The same applies when the hydraulic
system is commissioned or repaired
or when the oil is changed.
